Abstract
A motor driving method having a motor rotational direction feedback mechanism is performed by a motor driver. The motor driver includes a motor driving circuit, a motor state detecting circuit and a feedback circuit. The motor driver drives a motor. The motor state detecting circuit detects a rotational state of the motor. The rotational state of the motor includes a rotation direction. The feedback circuit sets at least one of a plurality of waveforms of a feedback signal according to the rotational state of the motor, and outputs the feedback signal.
